To all 'whom it may concer-n:

Be it known that l, DANIEL citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Drill-Hole-Cleaning Attachments for Hammer-Drills; and I do declare the following to be a fu11, clear1 and exactdescription of theinvention, such as 'will enable others skilledin the art to which .it appertains to make and use the same, reference being had. to the accompanying drawings, and to the letters and figures of referencev marked thereon, which forma part of this,` specification. i

My invention'relates t means for controlling the passage oi' air and water to the drill hole in hammer drills.

By virtue, of my improvement, the same valve that regulates the supply of water to Ythe drill hole, may also he utilized for cutting olii the-water and turning on the air whereby the one or the other fluid as may be desired maybe utilized for this purpose. In putting in down-holes it is preferred to utilize the water, while in drilling 11p-holes, it isprefer-red to' utilize the air since in the up-hole work the drill cuttings are washed out-in the .form o ein charge ofthe drill.'

water-as much as possible since it obviates or overeomesthe dust incident to the use of air alone lfor cleaning the drill hole. v,By virtue of my improvement the mechanism may be re Water and turn on the air or Vice versa without stopping the '-maehine. To this. end employ a three way valve adapted to-be so adjusted that one of its por with a passage leading from the-motive Huid supply of the main Valve, at the same time cutting off thewater supply. Again the valve may be so adjusted as to out oli"- supply and allow the passage 'of water to the drill'hole. i Having briefiy outlined my improved construction, I will proceed to describe thesame in detail'reference being made to the accom-- D panying drawing in which is illustrated an embodiment thereof. y In this drawing, Figure l is an elevation illustrating a hammer drill equipped .with my improvements, the drill steel and a por-` tion of the body or" the drill being shown in o improvements in f' mud and interfere with adily adjusted tp cutoff .the

|lfhe, same reference' `chareu'zters i indicate' thesame partsin all the views, Let the numeral .5 desi the drill and 6 the valvefor controlling thef motive iiuid supply thereto. Threaded into a reinforced part Tjof the casing, is-a valve' casing 8 in which 4is located a Valve piece 9.'y vConnected with this casing 8 is a mot-ive fluid supply conduit 10 whichv c with a motive fluid chamber l2 formed in the casing 8. This chamber is in communication with a chamber 18 ofthe main valve.' From' the chamber v13 a passage 14: leads to a ohamber'l fromwhich a passage 16 leads to the drill `:For the purpose of operating the. hammer. As the movement of the hammer has nothing to' do with this application further description ofthe mechanism will not'be required- A The valve' piece 9' has an opening' 17 leading downwardlyfroin its upper o1" larger extremity, this opening being in` communicet-ion with the chamber 12 and which theI 'motive IHuidentering'- through the conduit 10 is adapted to enter.. This opening'jlf? communicates with a short lateral vpassage 18 formed inthe valve andopening'` upon its' outerjsurfacei `whereby -in` communication 'with section. .Fi

asing and commugitudinal passage 2l" eatending` through thel sage 2S) in the valve piece extendsto the4 center thereof and communicates with a passage 30 which whenv the valve is ad justed as shown in Figs. l and 51's in coinmunication with the passage 20,' whereby Water entering the valve through the conduit 28 flows through the various passages which are incomniunication with the "pas-l Sage 27 of the drill steel. y A coil spring 31 is located in the chamber l2 and its opposite extremities engage the valve pieces 6 and 9 respectively.

- For the purpose of imparting a partial rotary movement in reverse directions to lthe drill body and drill steel, a handle 32 is provided. rlhis handle has a threaded reduced portion 33 screwed into a threaded opening formed in the outer extremity ot the valve casing valve piece 9. A sleeve 34 engages the body y of the handle 32 atene extremity and 'the outer portion of the valve casin1 t3 at its opposite extremity. rlhis sleeve is loosely mounted upon the said parts whereby it may be rotated thereon `t'or the purpose or" actuating the valve l) whereby the passages lof the valve through. which' the air and vrt ter pass, may be brougljit into communica tion with thopassagcs leading' to the drill steel as may be required. This sleeve connected with the valve piece 9 by means of a screw 35 Vwhich is threaded into the valve piece and passes through a slot 3G formed in the casing` 8 and extending oncfourth the distance around the said casing. Thehead ot the screw enters a slot 37 formed in the inner extremity ol' the sleeve 34, whereby the sleeve and screiiY are interloclred. Hence as the sleeve is given a quarter turn in the one direction or 'the other, the valve piece 9 is given a corresponding movement, whereby its passage ll or its passage and 30, may be brought into coinu'iunication will: the passage 2G as may be required. This sleeve may be readily actuated for the purpose, ot adjustiog the 'valve piece, since the handle l2 is normally grasped by the operator 'tor thc purpose ot rotating the drill. Non' who Icwr it desired to change the position oli the valve piece, it is only necessary for. the operator to more `his hand inwardly a short S in alinement with the' :lessees pose of changing from one to the other7 Withf out interrupting the operation of the drill. From the foregoing description the use and operation of my improved attachment 'will be readily understood.

Assuming thatit is desired to introduce Water to the drill hole, the valve piece 9 is ad-v justed as shown in the drawing whereby the waterconduitQ isinconununication with the angular passage 29, I30, the .latter being in communication with the passage 2O through Tvliich the Water flows to the passage 22 and thence throughuthe drill steel and into the drill hole as heretofore explained. New if it is desired to introduce an' or motive fluid to; the drill hole, the operator grasps the sleeve 34 Whichis loosel Y mounted upon the handle and casing 8 heretofore explained, and gives the latter aquarter turn, whereby Vthefpassage 17, 18 in the -valve piece is brought into communication with the water ronduit 28 being simultaneously 'cut ott.

lt will be understood that the valve piece 9 is manipulated independently of the main .valve 6, whereby the passage of fluid either air or Water to the drill hole may be accomplished Without interfering in any Way with the passage of motive fluid to the drill for the purpose of reciprocating the hammer. ln other Words the motive fluid conduit 1l) is in communication Ywith the chamber l2 at all times, the latter being in communicalion with the various passages leading tothe hammer chamber Having thus described my invention, what l claim l. ln a drill hole cleaninl;l attachment for motive Fluid actuated drills, the combination with the drill body, and means for supplying motive fluid thereto, oi a valve casing connected With the drill body throughivhich the motive iiuid passes to the body of the drill, said drill body and valve casing being provided with a main' passage leading from the valve chamber to the drill steel, a valve inminted in wsaid casing, a Water conduit connected with the casing, the valve being adjustable and provided either of which may be brought into corninunication 'with the main passage, whereby when the valve is moved into one position, the motive fluid passes therethrough to the Vdrill steel, while when the valve is moved into the other position the Water Hows through said passage, substantially as de scribed.
